RiRi took to the FRow, naturally, with her best friend Melissa Forde but the fashion show also drew in the likes of Margot Robbie, Maggie Gyllenhaal, Marion Cotillard, Allison Williams and Helena Christensen via chartered ferries. Anna Wintour and Grace Coddington too. Yes, really - this is how Raf Simons and the house of Dior roll.
Seriously A-list and all about Dior's cruise collection of fabulous feminine silhouettes (lots of silk scarves, tailoring, florals) - these were the hottest seats in the city last night.
LOVE RIRI'S STYLE? She definitely knows how to do sexy, street, statement AND stunning ladylike ensembles. Take a look through this gallery on her style file to see more starting way back when...
